Abstract
Abstract A surgical fastener is comprised of a center span with two locking arms extending therefrom, each locking arm containing an indentation adapted to receive a locking point and an indentation adapted to receive a locking nub. An inner bendable member extends from the center span terminating in a staple point member, the staple point member terminating in a tissue piercing point. An outer bendable member extends from the staple point member parallel to the inner bendable member, terminating in a locking point and locking nub. In the closed position the locking point of the outer bendable member locks into the indentation in the locking arm, to lock the staple in the closed position. In the open position the locking nub of the outer bendable member locks into the locking nub indentation in the locking arm to hold the staple in the open position.
